Correlates of gun-carrying among adolescents in south Louisiana.

In the majority of episodes of fatal interpersonal violence, the weapon used is a firearm. Amid frequent reports of youths carrying weapons, including firearms, we conducted a case-control study to identify risk factors for being charged with gun-carrying and gun-carrying, per se, among adolescents in Jefferson Parish, Louisiana. Cases were defined as incidents of gun-carrying among adolescents < 19 years of age, legally charged in the Jefferson Parish, Louisiana, juvenile court from January 1, 1992, through April 15, 1993. For each case, we randomly drew three age-, gender-, and school-matched control subjects from the enrollment rosters of the Jefferson Parish public schools and administered a questionnaire. The data set comprised 38 case subjects and 103 matched control subjects. Thirty (29%) control subjects reported gun-carrying. Both case subjects and gun-carrying control subjects reported self-defense (40%) as the main reason for gun-carrying. Most case subjects (25 [66%]) were African Americans, but only 8 (27%) gun-carrying and 27 (37%) non-gun-carrying control subjects were African Americans. Case subjects were significantly more likely than gun-carrying control subjects to report being African American (odds ratio [OR] = 5.3, 95% confidence intervals [CI] = 1.6, 17.5). In crude analyses, case subjects were more likely than non-gun-carrying control subjects to report adult-male unemployment among households with adult men, to foresee a likelihood to be shot in school, to have seen a shooting, to use marijuana, to watch television > 6 hours per day, and to be African American. After the effect estimates were adjusted in conditional logistic regression modeling, case subjects were more likely than non-gun-carrying control subjects to report adult-male unemployment among households with adult men, using marijuana, and watching television > 6 hours per day (OR = 8.6, 95% CI = 1.2, 61,2; OR = 11.7, 95% CI = 2, 70.2; and OR = 6.5, 95% CI = 0.8, 51.9, respectively). Gun-carrying control subjects were significantly more likely than non-gun-carrying control subjects to report their school not safe, having seen a shooting, using marijuana, and having fired a gun (OR = 9, 95% CI = 1, 82.1; OR = 7, 95% CI = 1.3, 38.2; OR = 6.8, 95% CI = 1.8, 25.5; and OR = 17, 95% CI = 1.8, 156.6, respectively). We found that gun-carrying was very common, and that adolescent youths who carry guns were more likely to have familiarity with guns and experience with or perception of an unsafe environment. Together, these lead to the conclusion that gun-carrying is a common response of youths who live in a risky environment, who do not have the social support to learn how to deal effectively with that risk, and who have access to guns, which they think may provide them with some protection.

Prevention of youth violence: rationale and characteristics of 15 evaluation projects.

Interpersonal violence is a major cause of injury, disability, and death, especially among youth. Evaluations of 15 youth violence-prevention projects are under way. Public health is concerned about health problems that need to be addressed via collective action. Public health involvement in addressing interpersonal violence among youths brings an emphasis on primary prevention, a systematic and scientific process, and integrative leadership. Few quantitative evaluations of violence-prevention projects have been done. The interventions are scientifically based and use a spectrum of strategies. Individually oriented strategies are more common than those directed toward peers, families, schools, or communities. Each project has a rigorous evaluation design. Twelve are randomized. Sample sizes range from 180 to 10,000. Participants range in age from 5 to 18 years, although most are in the middle-school years (11-14 years). At baseline, intervention and comparison groups are similar. Baseline data demonstrate high frequency of violent behavior, weapon carrying, and exposure to violence among the youthful participants. Field intervention and evaluation research is difficult and expensive. Difficulties encompass organizational programatic, and scientific issues; these difficulties reduce scientific interest and financial support for projects such as these. Public health has an important role to play in reducing violence. These projects will make important contributions to that task.

Building relationships and resilience in the prevention of youth violence.

Self Enhancement, Inc., is a grassroots, community-service organization working in the most disadvantaged high-risk community in Portland, Oregon. Its violence-prevention program targets middle-school and high-school students by providing classroom and community activities to these young people. These activities are designed to enhance protective factors and build resilience in youths to enable them to attain healthy and productive lives and to resist the threats of gangs, violence, and drugs. RMC Research Corporation works in partnership with Self Enhancement, Inc., to conduct research and evaluation on the effectiveness of its programs. The Self Enhancement, Inc., program works primarily at the individual student and interpersonal relationship levels. Resilience Theory and its culturally specific Relationship Model drive the formulation of specific strategies and activities. Program staff mentor each student through his or her preadolescent and adolescent years, promoting positive, prosocial norms and expectations for behavior through their peer group activities. The Self Enhancement, Inc., program consists of three major components: classroom, exposure, and proactive education. Classroom education focuses on anger management, conflict resolution, and problem solving. Exposure education consists of quarterly field trips to agencies and organizations in the Portland area that deal with the causes and consequences of violence in the community. Proactive education includes newsletters, student-run assemblies and conferences, and radio/ television public service announcements that communicate antiviolence messages. The evaluation plan is a longitudinal matched comparison group designed to assess the outcomes of the violence-prevention program. Key outcomes are protective factors, health-risk behaviors, and academic measures. Standardized assessment instruments (the Individual Protective Factors Index and the Youth Risk Behavior Survey) were administered to all students during winter 1994. The instruments will be readministered during the same period in the following two years of the project. School records were extracted to assess students' attendance and progress through their academic programs. Of the 326 seventh-, eighth-, and ninth-grade students participating in this study, 95% are African Americans and 51% are boys. The prevalence of fighting (56%) during the past 12 months is higher than that among African-American high-school students nationally, but weapon carrying (27%), alcohol use (30%), and marijuana use (18%) are the same or lower than national averages for this group. All baseline indicators are equivalent between the program and comparison groups with the exception of weapon carrying. Program students report carrying weapons more than do their comparison group counterparts. Baseline indicators of violence-related behaviors clearly indicate the need for intervention in this highly disadvantaged, African-American community. Through its historical presence and recent program development efforts, Self Enhancement, Inc., is well positioned to make a difference in the lives of these young people. The equivalence of program and comparison group students on baseline indicators of violence bodes well for an unequivocal assessment of program effectiveness over time.

Peacebuilders: a theoretically driven, school-based model for early violence prevention.

PeaceBuilders is a schoolwide violence-prevention program for elementary schools (K-5). A coalition of the Pima County Community Services Department, University of Arizona, and Heartsprings, Inc., (a Tucson-based company) are conducting a formal evaluation. Children who grow up to commit acts of violence show cognitive, social, and imitative differences from their peers. These characteristics can be ameliorated, most successfully through interventions that begin at an early age and involve multiple segments of the child's social experiences and interactions. PeaceBuilders activities are built into the school environment and the daily interactions among students, teachers, and administrative staff, all of whom are taught a common language and provided models of positive behavior, environmental cues to signal such behavior, opportunities to rehearse positive behavior, and rewards for practicing it. Four schools, one from each of four matched pairs, were randomly assigned to begin PeaceBuilders in Year 1. The remaining four schools begin in Year 2. Outcome assessments include student self-reports, standardized teacher reports, playground observations, and school and law enforcement records. Process assessments include school observations and surveys of teacher practices and satisfaction. Surveys were completed by 2,736 children. The sample is about 55% Hispanic, 26% Anglo, 14% Native American, and 4% African American. Among children in grades 3-5, during the past week 15% had been sent to the office for disciplinary problems, 13% tried to start a fight 27% hit someone, and 12% reported being threatened with a gun or knife. Violent behaviors and experiences are common among the studied children. A valid evaluation is underway of PeaceBuilders.

Trends in fatal firearm-related injuries, United States, 1962-1993.

OBJECTIVE: Our objective was to review historical trends in U.S. fatal firearm-related injuries for the years 1962-1993. METHODS: Using mortality data from the National Center for Health Statistics and population estimates projected from census data, we calculated national age-adjusted mortality rates and examined trends over the 32-year period. Data were also examined by type of firearm-related death (unintentional, suicide, homicide, legal intervention, and undetermined intention), race, gender, and age group. RESULTS: During the 32-year period, the total number of firearm-related deaths increased by 137%, from 16,720 in 1962 to 39,595 in 1993. Suicide and homicide were responsible for most firearm fatalities. Rates for both firearm suicides and firearm homicides increased over time, while rates for unintentional, legal intervention, and undetermined intention decreased. The highest rates and widest variation in total firearm-related mortality occurred among African-American men (35.2/100,000 to 84.5/100,000). Persons 15-19, 20-24, and > or = 75 years of age experienced the largest changes in rates during recent years; total firearm mortality was higher for the younger age groups (15-19, 20-24) during 1990 through 1993 than any other time during the 32-year period. CONCLUSIONS: These surveillance data help characterize trends over time and the magnitude of firearm-related mortality and identify groups at risk. However, further efforts to improve our understanding of firearm-related deaths and injuries, such as expansion of current surveillance to include information about morbidity associated with firearms and additional epidemiologic research to identify modifiable individual and societal risk factors, are necessary.

The impact of an elementary school-based violence prevention program on visits to the school nurse.

INTRODUCTION: In Tucson, Arizona, an elementary school-based violence prevention program (PeaceBuilders) was implemented during the 1994-1995 school year. Anecdotal evidence from school nurses suggested that children were visiting the nurse less often following the implementation of the program. We examined nurses' logs to assess whether the program had an impact on visits to the school nurse. METHODS: For the school years 1993-1994 and 1994-1995, the weekly number of nurse visits for all reasons, all injuries, and injuries caused by fights in each of the four PeaceBuilders schools were compared with those for three control schools. As part of a planned evaluation, schools had been matched on demographic factors and randomly assigned as intervention or control schools. RESULTS: Between 1993-1994 and 1994-1995, the rate of visits/1,000 student days decreased 12.6% in the intervention schools while remaining unchanged in the comparison schools. The same trend was detected for injury-related visits. Rates of fighting-related injuries changed little in the intervention schools but increased 56.0% in the control schools. An analysis of covariance confirmed that injuries and visits to nurses decreased in intervention schools relative to control schools. CONCLUSIONS: These data indicate that in the intervention schools, injuries and visits to the school nurse decreased over the two-year period and that the intervention may have contributed to this change. They also suggest that visits to the school nurses' office may be a useful tool to evaluate some types of elementary school-based violence prevention programs.
